Ataberk Tanzan
Data-Driven Application Operations Specialist
Karşıyaka
Summary
I hold a degree in Management Information Systems and have focused on application operations, error resolution processes, and ERP integrations using systems like Oracle, SAP, and NebimV3.
During my time at Etiya, I resolved issues using PL/SQL and reduced query times by 40%, leading to over 60 hours of monthly reporting efficiency.
At Martı Software, I worked as a Technical Manager Assistant, managing projects via Jira/Trello and providing QA/testing support to frontend and backend teams.
With my hybrid role supporting both customer-facing system operations and internal software development, I have specialized in process improvement and data-driven problem solving.
My goal is to advance my career as a digital systems manager who bridges technical knowledge with operational efficiency and fosters collaboration across teams.
